Tena Kennedy and Family from PEI? late 1800s - early 1900's

My great grandmother's name was Tena E Kennedy. She came to America around 1906 from Canada, married Arthur E Pinkham in 1909 in Somerville, MA.

I can not find her birthdate, only that it was around 1890. My grandmother (her daughter) said she came from PEI. Sadly, we are told Tena died at 36 years old during childbirth. So I dont think she ever returned to PEI to live? Is anyone willing to look this up for me? Is TENA short for any names back then? She would only have been about 15-16 years old when she left Canada for the US. Certainly she wouldnt be traveling alone? I'd love to know her parents name, reasons why she came to the US, any siblings, her nationality, etc. Any help would greatly be appreciated.Thanks, Melissa
